I Application filed October 9, 1914. Serial No. 865,823.

To all whom it may concern: I

Be it known that 1, JOHN A. Lnnrrorr, a citizen of the United States, and a resident of Wilmington, in the county of Newcastle and State of Delaware, have invented certain new and useful Improvements in Screens, of which the following is a specification.

lily invention relates to insect screensfor windows, porches, and the like, and one of the main objects thereof is to provide such devices which may be quickly and easily placed in position by unskilled persons, and which may be removed and replaced whenever desired without trouble.

A further object is to provide such devices which provide a maximum ventilating area relationship with said sides.

A further object is to'provide transverse bracing means to prevent the screen from buckling in the center; and further objects are to provide such devices which are constructed entirely of metal, are simple both in construction and installation, are well.

adapted for the purpose for which they are designed, may be readily removed and rolled into a compact bundle for storage, when not in use, and are com aratively inexpensive.

My invention is ully described in the following specification, of which the accompanying drawings form a part, in which the separate parts are designated by the same reference characters in each of the views,

. and in which Figure 1 is an elevation of the exterior of a window frame provided with my invention; Fig. 2 is a section taken on the line 22 of Fig. 1.;Fig. 3 is an enlarged fraginent of Fig. 1, inside thereof; Fig, 4: is a i" th t lfF' 8" section taien on e line 1 .1, 1g. 5 is a section taken on the line 55 of Fig. 3; Fig. 6 is another enlarged fragment or Fig. 1, on the inner side of the window; Fig. 7 is a section taken on the line 'Z'? 'of Fig. 6; Fig. 8 is asection taken on the line 88 of Fig. 6; and Fig. 9 is a sectional view of one edge of the screen, or-

rather the fabric thereof.

in the drawings forming a part of this application I have shown awindow frame having top and side members 10 and 11, respectively, and a sill 12, as well as upper and lower sashes l3 and 14, respectively.

What may be called the permanent parts of my invention comprise side guides and 16 which are formed of shcet metal bent.

upon-itself, as shown in Figs. 5 and 8, to

form a runway 17 and a planetary portion.

18 through which screws or the equivalent are passed to hold said guides to the corresponding sides of the window frame, and lower portion of the inner member of each guide is cut-away, as shown at 19, Figs. 2, 6 and 7, and the metal turned to form a bead thereat, and another permanent portion of the device consists of a screw-eye 20 arganged centrally in the upper frame memer l0.

The screen proper consists of the usual fabric, preferably metal, 21, the edges of which are preferably turned to present a smooth appearance, as shown in'Fig. 9, and I provide a plurality oi horizontally ar- 1 ranged brace rods 22, preferably til-shaped in cross section, as shown in Figs. 1, 2, 6, 7 and 8, and the ends of which are engaged in metal clips 23, shown in section in Fig. 8, as is also the wire mesh or fabric 21, and I locate said brace rods at as many suitable cints as desired, but not at the top or Jottoin edges ofthe screen.

Secured to the top and bottom edges thereof, as shown in Figs. 2, 3, l and 5, are stay members 24- and 25, respectively, each of which consists of sheet metal bent U- shape with the fabric therebetween, and the resultant bent Lshape, to torn; flanges, this being very clearly illustrated in Fig. d with respect to the upper stay member 24, and It also providetop and bottom rings 26 and 27,

respectively, and each of w ich in pivotal touches the top frame member 10, after which the screw-eye 20, which had been turned parallel with the upper sash 13, is turned at right-angles to the stay member 24 and under the flange thereof, thus forming a suspending means for the screen proper, the Weight of the lower stay member 25 maintaining the lower edge of the screen secure against the intrusion of insects, and it will be seen that the screen may be swung inwardly of the window up to the point 19 of the sideguides, to permit manipulation of blinds or shutters, or for brushing out dust and dirt, or for other reasons.

When it is desired to store the device, all that is necessary is to turn the screw-eye through an arc of 90 degrees. of a circle, and lower the screen through and out of the side guides, and rolling the same into a compact bundle, but it is not necessary to remove said guides nor screw-eye, as they are made of anti-rust material and are not in the way of the blinds or shutters, open or closed, but they may also be taken down if desired.

1 have illustrated the device as for the full length of a window frame, but I may provide them of but half length, for either the upper or lower portion of the frame, the stay members, in such event, bearing against the upper or lower stile of the upper sash in such use, but this is merely a matter of degree and does not alter the structural features described.

My device is long-lived, being made of metal, and, while I have shown certain details of construction, it will be obvious that changes thereover may be made, within the scope of the following claims, within the spirit of my invention.

Having fully described my invention,

ine astic what I claim as new, and desire to secure by Letters Patent, is

1. A device of the class described, comprising permanent side guides formed of metal, a screen movable therein, said guides being cut away to admit and, remove said screen, a flanged stay member at the top of said screen, a flanged stay member at the bottom of said screen, said stay members comprising a strip of metal bent into U formation to inclose the screen and being then bent at right angles at a point intermediate therewith to form a flange perpendicular to the plane of the screen, and a screw-eye supporting the upper stay, beneath the flange thereof to suspend said screen.

2. A device of the class described, comprising permanent side guides formed of metal, a screen movable therein, said guides being cut away to admit and remove said screen, a flanged stay member at the top of said screen, a flanged stay member at the bottom of said screen, means for suspending said screen, a plurality of transverse braces for said screen, and a socketed clip at each end of each of said braces, each of said clips comprising a strip of sheet metal bent into substantially U formation to inclose the corresponding end of a brace and the corresponding edge of the screen.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
